Description

Technical Field

[0001] The invention belongs to the technical field of belt conveyors, and in particular relates to an anti-deviation belt conveyor. Background Art

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries such as mining, metallurgy, electricity, building materials, tobacco, injection molding, printing, and food. They have the characteristics of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient implementation of programmed control and automated operation.

[0003] When conveying loose materials such as ore, coal, gravel, or other dusty goods on belt conveyors in cold weather, moisture in the air condenses on the conveyor belt, forming protrusions such as ice chips or ice cubes, mixed with impurities such as gravel and dust. These protrusions cannot melt away in time after conveying, causing the conveyor belt to slip on the roller surface and deviate, resulting in the conveyor belt deviation. When the conveyor belt deviates severely, it will cause material to scatter partially or entirely along the conveyor, reducing conveying efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0036] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0037] See also Figures 1 to 8 The embodiment of the present invention provides an anti-deviation belt conveyor, comprising:

[0038] The conveying mechanism 1 includes a conveyor belt 15;

[0039] The scraper mechanism 2 is installed on one side of the conveyor belt 15. The scraper mechanism 2 includes a scraper assembly 21 and an erasing assembly 23. The scraper assembly 21 includes a scraper 214. The erasing assembly 23 includes a liquid absorbing brush 231. The liquid absorbing brush 231 is installed on the side of the scraper 214 away from the scraping direction. The scraping direction is opposite to the return movement direction of the conveyor belt 15. For example, Figure 3 As shown, the return movement direction of the conveyor belt 15 is from left to right, and the scraping direction is from right to left;

[0040] When the scraper 214 moves to the maximum displacement along the scraping direction, the scraper 214 scrapes off the frozen inclusions on the surface of the conveyor belt 15, and the scraper assembly 21 squeezes out the liquid in the liquid absorbing brush 231, which is spaced apart from the conveyor belt 15.

[0041] When the scraper 214 moves to the initial position along the return movement direction of the conveyor belt 15 , the liquid absorbing brush 231 wipes off the remaining liquid on the surface of the conveyor belt 15 after scraping.

[0042] In one embodiment, if Figure 3 and Figure 5 As shown, the scraper assembly 21 further includes a scraper drive assembly and a support plate 213. The scraper drive assembly is transmission-connected to the support plate 213. A scraper plate 214 is installed on the side of the support plate 213 away from the scraper drive assembly.

[0043] For example, Figure 5 As shown, the scraper drive assembly includes a hydraulic cylinder 211 and a telescopic rod 212 . The output end of the hydraulic cylinder 211 is fixedly connected to the telescopic rod 212 , and one end of the telescopic rod 212 away from the hydraulic cylinder 211 is fixedly connected to a support plate 213 .

[0044] In one embodiment, please see Figures 3 to 6 The end of the scraper 214 away from the conveyor belt 15 is rotatably connected to the support plate 213. The side of the scraper 214 facing the support plate 213 is fixedly connected to a guide rod 235. The end of the guide rod 235 away from the scraper 214 passes through the support plate 213 and is slidably connected to the support plate 213.

[0045] The erasing assembly 23 further includes a limit seat 232, a baffle 233 and a first spring 234. The support plate 213 is symmetrically fixed with the limit seat 232. The limit seat 232 is provided with a limit slot. Figure 6 As shown, the limit groove is inclined, that is, the position of the end of the limit groove away from the support plate 213 is higher than the position of the end of the limit groove close to the support plate 213, the end of the liquid-absorbing brush 231 close to the conveyor belt 15 is embedded with a limit shaft, and the two ends of the limit shaft are slidably connected to the limit seat 232 through the limit groove, and the end of the support plate 213 close to the conveyor belt 15 is slidably connected with a baffle 233, and the baffle 233 is located on the side of the support plate 213 away from the scraper 214. A constraint rod is provided on the constraint rod. A first spring 234 is sleeved on the constraint rod. The end of the baffle 233 close to the scraper 214 is provided with an arc convex portion, and the arc convex portion of the baffle 233 is in frictional contact with the side of the scraper 214.

[0046] In the above embodiment, under the drive of the hydraulic cylinder 211, the telescopic rod 212 drives the scraper 214 to move along the scraping direction to the maximum displacement through the support plate 213. The friction between the scraper 214 and the conveyor belt 15 causes the scraper 214 to move along the direction of the material. Figure 3The position shown is rotated clockwise until the arc convex portion of the baffle 233 rubs against the side surface of the scraper 214. At this time, the area enclosed by the baffle 233, the scraper 214 and the support plate 213 is the liquid squeezing area. The scraper 214 pushes the liquid absorbing brush 231 to move in a direction relatively close to the support plate 213. The liquid absorbing brush 231 is guided by the limiting shaft and the limiting groove so that the liquid absorbing brush 231 is retracted into the liquid squeezing area. At this time, the liquid absorbing brush 231 is spaced apart from the conveyor belt 15. The scraper 214 and the support plate 213 squeeze the liquid absorbing brush 231 to squeeze out the liquid in the liquid absorbing brush 231. In addition, the setting of the baffle 233 effectively prevents the residual liquid from splashing onto the conveyor belt 15 during the squeezing process, thereby improving the wiping effect.

[0047] When the support plate 213 drives the scraper 214 to move to the initial position along the return direction of the conveyor belt 15 under the reverse drive of the hydraulic cylinder 211, the scraper 214 is prevented from moving along the return direction of the conveyor belt 15 by friction between the scraper 214 and the conveyor belt 15. Figure 6 The scraper 214 rotates counterclockwise in the direction shown, and moves the liquid-absorbing brush 231 outward until the liquid-absorbing brush 231 rubs against the conveyor belt 15, that is, the liquid-absorbing brush 231 is in the wiping position, so that the liquid-absorbing brush 231 can wipe off the remaining liquid on the surface of the conveyor belt 15 after scraping, and prevent the residual liquid from freezing on the conveyor belt 15 again, causing the conveyor belt 15 to slip and deviate from the contact with the roller surface.

[0048] In one embodiment, if Figure 6 As shown, a plurality of squeezing holes 236 are provided on the support plate 213 , so that when the liquid-absorbing brush 231 is squeezed to discharge liquid, the squeezed liquid is quickly discharged to the outside of the squeezing area through the squeezing holes 236 .

[0049] For the relative movement position of the scraper 214 on the surface of the conveyor belt 15, please refer to Figure 7 and Figure 8 , where S T刮 S represents the scraping distance of the scraper 214 relative to the surface of the conveyor belt 15 in one movement cycle. T擦 It represents the wiping distance of the liquid absorbing brush 231 relative to the surface of the conveyor belt 15 in one movement cycle. Figure 7 The indication is 1 / 2S T刮 =S T擦 situation, Figure 8 The indication is 1 / 2S T刮 <S T擦 <S T刮 situation, combined with Figure 7 and Figure 8 It is not difficult to find that only 1 / 2S is required T刮 ≤S T擦 <ST刮 Under the continuous movement of the conveyor belt 15, the frozen inclusions on the surface of the conveyor belt 15 can be scraped off and the residual liquid can be wiped off, so as to solve the problem in the prior art that the conveyor belt 15 slips on the surface of the roller due to the frozen inclusions and deviates.

[0050] In one embodiment, please see Figures 3 to 6 The anti-deviation belt conveyor also includes a blowing component 22, which is used to blow away the frozen inclusions on the scraper 214. The blowing component 22 includes a heating box 221, a first connecting pipe 222, a second connecting pipe 225, a pump air box body 223 and a push plate 224. The output end of the heating box 221 is connected to the first connecting pipe 222, and the end of the first connecting pipe 222 away from the heating box 221 is connected to the input end of the pump air box body 223, and the output end of the pump air box body 223 is connected to the second connecting pipe 225, wherein the scraping surface of the scraper 214 close to the conveyor belt 15 has an arc recess, and the scraper 214 is provided with a blowing port 226 at the position of the arc recess, and the air inlet end of the blowing port 226 is connected to the end of the second connecting pipe 225 away from the pump air box body 223. The air outlet end of the material port 226 is arranged corresponding to the scraping surface of the scraper 214, wherein a first one-way valve is embedded in the connection between the first connecting pipe 222 and the pump air box body 223, and a second one-way valve is embedded in the connection between the second connecting pipe 225 and the pump air box body 223. The first one-way valve is used to control the one-way flow of gas in the first connecting pipe 222 to the pump air box body 223, and the second one-way valve is used to control the one-way flow of gas in the pump air box body 223 to the second connecting pipe 225. A push plate 224 is slidingly connected to the pump air box body 223, and one end of the push plate 224 close to the support plate 213 passes through the pump air box body 223 and is slidingly connected to the pump air box body 223, and the side circumferential surface of the push plate 224 is tightly fitted with the inner wall of the pump air box body 223, and the end of the push plate 224 located outside the pump air box body 223 is fixedly connected to the support plate 213.

[0051] In the above embodiment, when the scraper 214 moves along the scraping direction, the support plate 213 drives the push plate 224 to move left, so as to transport the hot air in the heating box 221 to the pump air box 223 through the first connecting pipe 222, and when the scraper 214 moves along the return movement direction of the conveyor belt 15, the push plate 224 transports the hot air in the pump air box 223 to the blowing port 226 through the second connecting pipe 225 to blow away the frozen inclusions scraped off the surface of the scraper 214.

[0052] For example, Figure 6As shown, a preheating chamber 227 is provided in the scraper 214, and the end of the second connecting pipe 225 away from the pump air box 223 is connected to the preheating chamber 227, and the air inlet end of the blowing port 226 is connected to the second connecting pipe 225 through the preheating chamber 227. The preheating chamber 227 is used to control the temperature of the scraping surface of the scraper 214, so that the frozen inclusions scraped off by the scraper 214 are not easily frozen on the scraper 214, that is, the adhesion between the frozen inclusions and the scraper 214 is reduced, which is conducive to the frozen inclusions sliding quickly away from the scraper 214 under the blowing of the blowing port 226, thereby improving the sweeping effect.

[0053] In one embodiment, please see Figures 3 to 5 The anti-deviation belt conveyor also includes an ice-breaking component 24 and an ice-melting component. The ice-breaking component 24 includes a toothed plate 241, a limiting rod 242, a limiting bracket 243, a second spring 244 and a protrusion 245. The toothed plate 241 is fixedly mounted on the support plate 213. The setting direction of the toothed plate 241 is consistent with the driving direction of the scraper drive assembly. The toothed plate 241 is in friction with the toothed end of the limiting rod 242. The end of the limiting rod 242 away from the toothed plate 241 passes through the limiting bracket 243 and is in contact with the limiting The positioning bracket 243 is slidably connected, and the position of the limiting bracket 243 is fixed relative to the pump air box body 223. The limiting rod 242 is located at the end of the side of the limiting bracket 243 away from the toothed plate 241 and is fixedly connected with a protrusion 245. The limiting rod 242 is located between the protrusion 245 and the limiting bracket 243 and is sleeved with a second spring 244. The convex part of the protrusion 245 is in frictional contact with the surface of the conveyor belt 15, and the protrusion 245 is used to knock and break the frozen inclusions on the return conveyor belt 15.

[0054] Moreover, illustratively, Figure 3 and Figure 4 As shown, the ice melting assembly is used to heat the return conveyor belt 15, and the ice melting assembly includes an ice melting hood 25 and an air pump 26. The input end of the air pump 26 is connected to the third connecting pipe, and the end of the third connecting pipe away from the air pump 26 is connected to the heating box 221. The output end of the air pump 26 is connected to the fourth connecting pipe, and the end of the fourth connecting pipe away from the air pump 26 is connected to the ice melting hood 25. The conveyor belt 15 has a side for conveying materials as the conveying surface, and the ice melting hood 25 is arranged on the side of the conveyor belt 15 away from the conveying surface, and the ice melting hood 25 is spaced apart from the conveyor belt 15.

[0055] In the above embodiment, the reciprocating movement of the support plate 213 drives the toothed plate 241 to rub against the toothed end of the limit rod 242, and under the reset action of the second spring 244, the protrusion 245 intermittently and periodically knocks the conveyor belt 15 to pre-process the large-scale frozen inclusions in advance. Moreover, the conveyor belt 15 passing under the ice melting cover 25 is continuously heated by the ice melting cover 25 to reduce the adhesion between the frozen inclusions and the conveyor belt 15. Combined with the action of the ice breaking assembly 24, it is beneficial to reduce the working intensity of the subsequent scraper 214 scraping the material.

[0056] For example, Figure 1 and Figure 2 As shown, the anti-deviation belt conveyor further includes a collecting box 3, which is arranged below the conveyor belt 15, and the scraping mechanism 2 is installed in the collecting box 3, and the collecting box 3 is used to collect the frozen inclusions scraped off and the residual liquid wiped off. For example, Figure 1 and Figure 3 As shown, the hydraulic cylinder 211 , the pump box 223 and the limiting bracket 243 are respectively fixedly arranged on the collection box 3 .

[0057] The conveying mechanism 1 also includes a motor 11, upper rollers 12, lower rollers 14, and side guards 13. The conveyor belt 15 is sleeved on the active drive roller and the driven drive roller. The output end of the motor 11 is fixedly connected to the active drive roller. The side guards 13 are symmetrically mounted on both sides of the conveyor belt 15. Along the forward direction of the conveyor belt 15, multiple upper rollers 12 are evenly arranged, and the ends of the multiple upper rollers 12 are rotatably connected to the side guards 13. Along the return direction of the conveyor belt 15, multiple lower rollers 14 are evenly arranged, and the ends of the multiple upper rollers 12 are rotatably connected to the side guards 13. The surfaces of the multiple upper rollers 12 and the surfaces of the multiple lower rollers 14 respectively frictionally conflict with the conveyor belt 15. The side guard limiters of the side guards 13 effectively prevent the conveyed materials from slipping off the conveyor belt 15.

[0058] For example, Figures 1 to 4 As shown, the heating box 221 and the air pump 26 are respectively installed on the side baffle 13. In other embodiments, the heating box 221 and the air pump 26 are respectively installed on the outside of the collection box. The staff can flexibly arrange them according to the application environment of the conveyor, which is not limited here.

[0059] It should be noted that when the conveyor is in use, the motor 11 is first started, the material to be conveyed is placed on the conveyor belt 15, and the heating box 221, the air pump 26 and the hydraulic cylinder 211 are started. Under the drive of the hydraulic cylinder 211, the support plate 213 moves from the initial position along the scraping direction, and the scraper 214 scrapes the frozen inclusions on the surface of the conveyor belt 15. The friction between the scraper 214 and the conveyor belt 15 causes the scraper 214 to move along the direction of the material. Figure 3 The position shown is rotated clockwise until the arc convex portion of the baffle plate 233 rubs against the side surface of the scraper plate 214, and the scraper plate 214 pushes the liquid absorbing brush 231 back to the liquid squeezing area. At this time, the liquid absorbing brush 231 is spaced apart from the conveyor belt 15. As the liquid squeezing area continues to shrink, the scraper plate 214 and the support plate 213 squeeze the liquid absorbing brush 231 to squeeze out the liquid in the liquid absorbing brush 231. In addition, the setting of the baffle plate 233 effectively prevents the residual liquid from splashing onto the conveyor belt 15 again during the squeezing process, thereby improving the wiping effect. Moreover, during this process, the push plate 224 moves left to transport the hot air in the heating box 221 to the pump air box 223.

[0060] Then, when the scraper 214 moves in the return direction of the conveyor belt 15, the scraper 214 pulls the liquid absorbing brush 231 outward until the liquid absorbing brush 231 rubs against the conveyor belt 15, so that the liquid absorbing brush 231 wipes off the residual liquid on the surface of the conveyor belt 15 after scraping, and prevents the residual liquid from continuing to freeze on the conveyor belt 15, causing the conveyor belt 15 to slip and deviate from the contact with the roller surface; moreover, during this process, the push plate 224 moves right, and the hot air in the pump air box 223 is transported to the preheating chamber 227 and the blowing port 226, so as to blow away the frozen inclusions scraped off by the scraper 214 from the scraper 214, and prevent the frozen inclusions from refreezing on the scraper 214, thereby improving the scraping efficiency;

[0061] In addition, during the periodic reciprocating movement of the support plate 213, the conveyor of the present invention also heats the conveyor belt 15 passing under the ice melting cover 25 through the ice melting cover 25, thereby reducing the adhesion between the frozen inclusions and the conveyor belt, and with the help of the friction between the toothed plate 241 and the limit rod 242, the protrusion 245 intermittently and periodically knocks the conveyor belt 15 to pre-crush or remove some of the frozen inclusions, thereby reducing the scraping strength of the subsequent scraper 214, and the scraped frozen inclusions and the wiped-out residual liquid are uniformly collected in the collection box 3 to ensure a clean working environment.

[0062] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
